Just a quick question. How would you figure out what your total range haste is? I have 22% from my quiver, 8% from a rune, and 6% from aura. I was told in game that it is not additive. Anyone care to help out? Much appreciated.

Start with your 58 bow, which has a base 46 delay.

46/1.22 = 37.70. Then that/1.08 = 34.91. Then that/1.06 = 32.93 effective delay. Or put it another way, 39.69% haste increase, which is the number I gave in civil chat.

Yes, those stack. What doesn't stack is an epic quiver range haste aura (such as the epic 78 or one of the epic 99 quivers) with the range haste aura gem. The basic quiver haste does stack, though.

No, those don't stack, just as quivers with range haste aura don't stack with the range haste aura gem. For example, the melee and range slow aura of the epic 88 quiver doesn't stack with a sloth aura gem.
